Item 1, New License.
While the U.S. Army has not determined that the Atomic Energy Act (Act) requires a license in
this situation, we are providing this application to promote cooperation between our agencies and
to the extent required by the Act.
Item 2. Name and Mailing Address of Applicant
US Army Installation Command
25 1 1 Jefferson Davis Highway
Arlington, VA 22202
Item 3. Address Where Licensed Material Will Be Used or Possessed
This license will authorize the possession of residual quantities of depleted uranium system at
US Department of Army Installations.
The initial discovery of depleted uranium from the M 101 spotting round was at locations within
Hawaii and at Fort Hood, TX. Nonetheless, presence of depleted uranium may be determined to
exist at additional installations. Installations identified as potential sources for depleted uranium
contamination will be subjected to additional investigations to consist of historical site
assessments and radiological surveys/ evaluations as necessary to confirm the existence of
depleted uranium at a given facility. Additional installations where the M 101 spotting round has
been found include: Fort Benning, GA; Fort Campbell, KY; Fort Carson, CO; Fort Hood, TX;
Fort Knox, KY; Fort Lewis, WA; Fort Riley, KS; Schofield Barracks, HI; and Pohakuloa
Training Area, HI. Installations currently subject to further investigation include: Aberdeen
Proving Ground, MD; Fort Dix, NJ; and Makua Military Reservation, HI. The NRC will be
notified upon confirmation that depleted uranium is present at a given installation and that
installation will then be incorporated into this permit.
A common characteristic of the sites where the M 101 spotting round fragments are located is
that they are well within the installation boundary and are located in an impact area where access
is strictly controlled. These impact areas contain a number of other hazards such as unexploded
ordinance which require restricted access and additional training prior to entry. This limits the
potential for inadvertent exposure and ensures members of the general public, to include Army
civilians and soldiers, are not directly exposed to the material.
Item 4. Name Of Person To Be Contacted About This Application
Item 5. Radioactive Material:
a. Element and Mass Number: Depleted uranium ( 238 U, 235 U, and 234 U); mass number (92)
M101 spotting round. A total of 75,318 rounds were originally produced. "Each depleted
uranium projectile body weighed 3,180 ± 25 grains" (USACE 2007). This equates to about 206
g or 0.45 lb. Given a composition of 92 percent depleted uranium and 8 percent molybdenum,
2926 grains or 190g of depleted uranium was contained within each round.
b. Chemical and/or physical form: Any
c. Maximum amount that will be possessed: 8000 Kg (17,637 lbs) of depleted uranium.
The M101 spotting round was manufactured and distributed under NRC License SUB 459. "In
the 1970's, approximately 44,000 DU rounds were demilitarized under the Remington Arms
license by firing into the 600- Yard Bullet Catcher." (Cabrera 2006) In addition, about 2000
rounds were fired at LCAAP in the 1960's for lot testing. As such, a total of about 46,000
rounds can be accounted for out of a total production of 75,3 18 leaving about 29,300 rounds for
distribution to Army organizations. Details with regard to the specific number of rounds issued
to a given installation, previously recovered from ranges or disposed of as radioactive waste is
not currently known. Given 29,318 rounds each containing 206 grams of alloy equates to an
actual maximum possession quantity of about 6040 Kg of alloy containing about 5560 Kg of
Item 6. Purpose for Which Licensed Material will be Used:
This U.S. Nuclear Regulatory Commission (NRC) license application is for authorization to
possess and manage depleted uranium present at US Army installations as a result of previous
use of depleted uranium. Specific functions to be performed under the license will be limited to
radiological surveys as necessary to fully characterize the nature and extent of contamination
and, when appropriate, to obtain information necessary to support development of
decommissioning plans. Depleted uranium possessed pursuant to this license may also be
subjected to disposal by transfer to a properly permitted/licensed disposal facility.
Item 7. Individual(s) Responsible for Radiation Safety Program and Their Training
Executive management and the Radiation Safety Staff Officer (RSSO) will work as a team to
oversee the Radiation Safety Program for this NRC license. The Army Radiation Safety Officer
(ARSO) directs the Army Radiation Safety Program on behalf of the Director of Army Safety
(DAS AF) for all radiation sources used or possessed by the Army, to include those authorized
under this license, and fulfills the functions specified in paragraph l-4m, Department of the
Army Pamphlet 385-24. In this capacity the ARSO promotes good radiation safety practices
throughout the Army, provides radiation safety consultation and resolves radiation safety issues.
The ARSO is a senior professional health physicist with extensive education, training and
experience in health physics to include radiation protection aspects involving depleted uranium.
Pursuant to paragraph l-4i, Department of the Army Pamphlet (DA Pam) 385-24, (Attachment
1) Commanders will ensure command compliance with conditions of this NRC license. This
will be accomplished in part by designating, in writing, a trained Health Physicist/RSSO who
will be responsible for day-to-day operation of the radiation safety program. The RSSO will
have, as a minimum, a college degree at the bachelor level in a physical or biological science,
mathematics or engineering and training and experience commensurate with the scope of the
license to include specific training involving depleted uranium. Consistent with NUREG-1556,
training will be from "a formal course designed for RSOs presented by an academic institution,
commercial radiation safety consulting company, or a professional organization of radiation
protection experts". Training will include the following subjects:
• Radiation Protection Principles
• Characteristics of Ionizing Radiation
• Units of Radiation Dose and Quantities
• Radiation Detection Instrumentation
• Biological Hazards of Exposure to Radiation
• NRC Regulatory Requirements and Standards
• Hands-on use of radioactive materials.
In addition to the RSSO, each Garrison Commander will designate, "in writing, a trained
Garrison RSO" in accordance with paragraph 1-41, DA Pam 385-24. The Garrison RSO
"establishes and directs the garrison Radiation Safety Program (to include a written Radiation
Safety Program document)" and performs the functions detailed in paragraphs l-4p, q, and r, DA
Pamphlet 385-24, as applicable. Further, each RSO "designee is trained (and periodically
retrained, as necessary) to a level commensurate with the Radiation Safety Program scope and
responsibilities, (see chap 7)." (paragraph l-4k(2)(a), DA Pam 385-24). "Acceptable courses
for unit and garrison radiation safety officers are offered by the U.S. Army Chemical School,
MEDCOM, NGB, and Army Materiel Command licensees." (paragraph 7-2, DA Pam 385-24).
The ARSO is responsible for identifying qualifying courses for Army RSOs and may approve
alternate training if they meet equivalent standards of the above listed courses.

Item 8. Training for Individuals Working in or Frequenting Restricted Areas:
Paragraph l-4k, DA Pam 385-24 mandates that each commander or director is responsible to
ensure "that all personnel occupationally exposed to radiation receive appropriate radiation
safety training commensurate with potential work place hazards". This requirement is consistent
with and implements the requirements of 10 CFR 19 such that all individuals authorized
unescorted access to restricted areas in which depleted uranium is present will receive training to
meet the requirements of 10 CFR 19 prior to working in or frequenting such areas. This site-
specific training will be performed by the Unit and/or Garrison Radiation Safety Officer or their
Item 9. Facilities and Equipment.
The Department of Defense (DOD) has a broad range of radiological facilities and equipment
and associated capabilities to include a variety of different military and commercial Radiation
Detection, Identification and Computation (RADIAC) instruments. DOD also has significant
organic radioanalytical capabilities. Each U.S. Army Command has assigned RADIAC
instruments (and qualified users) as needed to fulfill a variety of tactical and non-tactical nuclear
and radiological missions. Although the specific instruments will vary to some extent, military
RADIAC instruments generally available at all Army installations typically include the
AN/VDR-2 Radiac Set and the AN/PDR-77 Radiac Set. Army organizations may also possess a
wide variety of different types of commercial RADIAC instrumentation or older model sets such
as the AN/PDR-27.
Although the limited emissions from depleted uranium are such that external dosimetry is not
generally required, in the event that dosimetry devices are determined to be appropriate, such
devices will be obtained from the U.S. Army Dosimetry Center, Redstone Arsenal, AL 35898-
Item 10. Radiation Safety Program.
Army Regulation 385-10, entitled "The Army Safety Program", provides "policy on Army safety
management procedures with special emphasis on responsibilities and organizational concepts."
"This regulation applies to the Active Army, the Army National Guard/Army National Guard of
the United States and the Army Reserve unless otherwise stated." Chapter 7 entitled "Radiation
Safety Management" "prescribes DA safety policy and processes for the Army radiation safety
function" (See Attachment 4). AR 385-10, Chapter 7, is augmented by Department of the Army
Pamphlet (DA Pam) 385-24. DA Pam 385-24 "establishes procedures and guidance for the safe
use, storage, licensing, disposal, transportation, safety design, and inventory control of ionizing
and non-ionizing radiation sources. It also provides radiation exposure standards and dosimetry
and accident reporting instructions. Its objective is to ensure safe use of radiation sources and
compliance with all applicable Federal and Department of Defense (DOD) rules and
regulations." (DA Pam 385-24, paragraph 1-1)
Paragraph 1-4, DA Pam 385-24 stipulates that Each Commander or Director or an organization
requiring an RSO must have "Established written policies and procedures to ensure compliance
with applicable Federal, DOD and Army radiation safety regulations and directives" and
Individual(s) responsible for radiation safety program and their training and experience are listed
in Item 7. Specific duties and responsibilities of Garrison RSOs, all RSOs and unit RSOs are
specified in paragraphs l-4p, q, and r, respectively. The responsibilities of RSOs may not be
transferred to other individuals. Many tasks and duties associated with managing the program
may be assigned or delegated to other qualified individuals; however, the responsibility for these
tasks and duties is with the RSO. NRC does recognize that a qualified individual will have to fill
in for the RSO when the RSO will be away for short periods of time for professional
conferences, vacation, or illness. However, this should not occur for extended or indefinite
periods of time. Consideration must also be given to how the RSO will be contacted in the event
of an emergency.
As derived from circa 1968 'Typical Davy Crockett Weapon System Range Layout," the impact
area for the Davy Crockett is about 400m by 500m or about 200,000 m 2 . Distribution of 560 Kg
(0.2016 Ci) (assuming 10 percent of the total DU) of depleted uranium in surface soils (top 15
cm (6 inches) would result in distribution in a total of volume of 3.0 X 10 10 cm 3 .
M28 Davy Crockett Weapon System Range Layout
For a soil density of 1.5 g/cm the soil concentration would equate to an average concentration of
about 4.5 pCi/g if 10 percent of all rounds that are not currently accounted for were, in fact, fired
at a given Army range used for Davy Crockett training. This concentration is significantly lower
than the screening values for uranium (13,8 and 14 pCi/g for 234 U, 235 U and 238 U, respectively)
specified in Volume 2, Appendix H, NUREG-1757. Further, given that "Only the ground water
pathways are affected by the total inventory of residual radioactivity, including that deeper than
15 centimeters. The direct, inhalation, ingestion and crop pathways are determined by
concentration only, not total inventory." (Paragraph G.2.1, Volume 2, NUREG-1757). This
should represent an appropriate bounding condition. As such, one can reasonably conclude that
potential doses due to the presence of depleted uranium from the M 101 Spotting Round used by
the M28 Davy Crockett Light Weapon are expected to be much less than general public exposure
limits specified in 10 CFR 20. 1301 and are likely to be some small fraction of the 25 mrem/yr
prescribed by 10 CFR 20.1402. (Preliminary assessment using RESRAD Version 6.3 results in
an estimated dose of 0.5 mrem/yr for the stated criteria with model default parameters. If all
unaccounted rounds were, in fact, fired at one of the Army's ranges used for Davy Crockett
training, RESRAD Version 6.3 results in an estimated dose of 5 mrem/yr for the stated criteria
with model default parameters. (These doses were derived using all RESRAD default pathways)

Consistent with the philosophy of maintaining radiation exposures as low as reasonably
achievable, the Radiation Safety Program for depleted uranium from the Davy Crockett weapon
system will consist of identification of the area(s) containing depleted uranium as a result of the
use of the Davy Crockett weapon system; imposition of access restrictions with appropriate
radiological monitoring requirements pending assessment of radiological conditions within a
given affected area; the performance of scoping and characterization surveys to delineate the
affected area (subject to precautions required due to the presence of unexploded ordnance); and
investigation of remedial alternatives for the affected area. The NRC will be appropriately
notified upon identification of areas containing depleted uranium from the Davy Crockett
weapon system. In addition, actions to address the presence of depleted uranium will be fully
coordinated with the NRC upon determination that contamination exists at a given installation or
Migration of depleted uranium has been and continues to be extensively studied at a variety of
military installations to include Aberdeen Proving Ground, MD, Jefferson Proving Ground, IN,
Lake City Army Ammunition Plant and the Iowa Army Ammunition Plant. Available
information indicates that depleted uranium metal generally remains in the immediate vicinity
where initially deposited with limited migration over the periods that the materials have been
present. The potential for DU to migrate depends on a number of factors to include chemical
form of the uranium; chemical characteristics of soil including pH; proximity to surface water
bodies; depth to groundwater; and topography/terrain. Given that migration would generally
distribute uranium over a larger area thus reducing its concentration and that dose depends
primarily on the average concentration, migration would tend to lower doses but to increase the
potential for low level exposures.
Radiological surveys of areas determined to be contaminated as a result of the M101 spotting
round will be subject to appropriate radiological investigations. These surveys will most
commonly involve 2" X 2" or similar Nal(Tl) scintillation detectors. The scan MDC for depleted
uranium (0.34% U-235) as specified in Table 6.4, NUREG-1507, is about 56 pCi/g with a
weighted cpm/uR/h of 3,790. Comprehensive studies have been performed to assess the ability
of such detectors to assess the existence of depleted uranium metal. These studies indicate that a
DU penetrator fragment as small as 0.37 cubic inches (6 cubic centimeters) can be located easily
on the soil surface during a typical scan (assuming an investigation threshold of 2,000 cpm above
background). Similar evaluation indicates that a DU penetrator fragment as small as 0.61 cubic
inches (10 cubic centimeters) can be located easily below 2 inches (5.1 centimeters) of soil
during a typical scan (again assuming an investigation threshold of 2,000 cpm above
background). (SAIC 2005).
Since each site has unique geological and climatic conditions, whether a site specific
environmental monitoring plan will be necessary for every installation where M101 spotting
round fragments are located will be considered, subject to availability of funding. Any
monitoring plan must be agreed to by both the Army and the NRC. Where feasible and where
existing environmental monitoring plans are in place to demonstrate that other constituents of
concern are not being transported off range, DU will be added to those monitoring efforts.
11. Waste Management.
Screening levels for clearance are defined in Table 5-2, DA-PAM 385-24. When depleted
uranium contamination exceeding these screening levels are confirmed at an Army installation,
then the Army will coordinate with the NRC in developing appropriate site-specific action
incorporating the requirements of DA-PAM 385-24. When disposal is necessary, the material
will be transferred to an authorized disposal site.
